Upgrading from version 0.10 to 1.1.2 will break a lot of packages that depend on ffmpeg...still I have build the latest stable 0.10.7 for the 0.10 release branch...you can get it from the untested repo via gslapt/slapt-get...

So far upgrading to ffmpeg-0.10.7 only break the default MPlayer but there is an update version in the repo that work well with ffmpeg-0.10.7...so I bet it is ok to upgrade to 0.10.7still I am not sure will it solve your linphone problem...

I installed ffmpeg 10.7 and then recompiled linphone 3.6.1 (VIDEO=yes) and installed it, but linphone still shows video disabled and is still intolerably slow in loading linphonerc when it contains my contacts.

But on a happier note, etm still works. Mplayer seems to work but shows dependency error when I try to install latest smplayer.
